If your eSIM is not working after restoring a backup, the most common reasons are that the eSIM profile was not transferred with the backup, the line is disabled, mobile data settings changed, roaming was turned OFF, or the phone needs to re-register on the network.
This is a common problem after moving to a new phone or restoring an old device. Everything else may return normally — apps, photos, contacts, messages — but the eSIM does not work as expected.
The good news: in many cases, the eSIM is still available or can be restored quickly.
You may notice:
- eSIM missing after restore
- No Service after backup restore
- main SIM works but travel eSIM does not
- eSIM visible but no data
- phone asks to add eSIM again
This guide explains exactly why your eSIM is not working after restoring backup, how to fix it quickly, and how to avoid issues during future device restores.
Quick answer: Check if the eSIM profile transferred, enable the line, set it as the data SIM, turn roaming ON, restart the phone, and reinstall the eSIM if needed.
1. Backups Often Do Not Fully Restore eSIM Profiles
This is the #1 reason.
Many cloud or local backups restore apps and data, but not always the active eSIM profile itself.
Depending on the device and OS version, you may need to re-add the eSIM manually.
Fix:
- Open SIM / Cellular settings
- Check if the eSIM profile exists
- If missing, add it again

Fix:

Fix:
- Select the travel eSIM for mobile data

Fix:
- Open eSIM settings
- Turn Data Roaming ON

5. Phone Needs Network Re-Registration
After a restore, the modem may need time to reconnect.
Fix:
- Restart the phone
- Wait 5–10 minutes
6. eSIM Was Tied to the Old Device Session
Some plans need a fresh install on the new device instead of restore cloning.
Fix:
- Delete incomplete profile
- Install again using QR code
7. Backup Was Incomplete
If the restore was interrupted, SIM settings may not transfer correctly.
Fix:
- Finish setup completely
- Reconnect to Wi-Fi
8. Software Update Needed
Some restore issues disappear after updating iOS or Android.
Fix:
- Install latest software update

Dual SIM phones may prioritize the physical SIM after restore.
Fix:
- Main SIM for calls
- Travel eSIM for data

Some travel eSIMs activate fully only in supported countries.
Fix:
- Try again after arrival
